value of front s caliper set mismatched
 

I have a pr of alloy s calipers that were removed from a parted 70 911 of a friend. One is the later greenish annodized and one earlier silver one. Pistons move but would put new rubber kits. What can these be worth in todays climate?

Clean and ready to use = $500-600/pr and should move them quick. More if they were a matched set and/or freshly restored to the same finish.

As-is (need rebuild kit) and perhaps still dirty = $400 and might move a slower.

Used parts are often valued heavily based on condition. Some don't care because they will restore and 'get their hands dirty' anyway. Others value ready to bolt on with a big premium.
